I've been noticing a strange rattling sound from the iDrive 8.5 system and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

Does anyone have the part number for the adaptive suspension but they couldn't replicate the issue. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.
